Kauai
Ancient Hawaiians were water sports fanatics—they invented surfing, after all—and that propensity hasn't strayed far from today's mind-set. Even if you're not into water sports or sports in general, there's only a slim chance that you'll leave this island without getting out on the ocean, as Kauai's top attraction—Napali Coast—is something not to be missed.
For those who can't pack enough snorkeling, fishing, body boarding, or surfing time into a vacation, Kauai has it all—everything except parasailing, that is, as it's illegal to do it here (though not on Maui, the Big Island, or Oahu). If you need to rent gear for any of these activities, you'll find plenty of places with large selections at reasonable prices. And no matter what part of the island you're staying on, you'll have several options for choice spots to enjoy playing in the water.
One thing to note, and we can't say this enough—the waters off the coast of Kauai have strong currents and can be unpredictable, so always err on the side of caution and know your limits. Follow the tagline repeated by the island’s lifeguards—"When in doubt, don’t go out."
Kaui's outdoor recreation options extend well beyond the sand and surf, with plenty of activities to keep you busy on the ground and even in the air. You can hike the island's many trails, or consider taking your vacation into flight with a treetop zip line. You can have a backcountry adventure in a four-wheel drive, or relax in an inner tube floating down the cane-field irrigation canals.
Before booking tours, check with your concierge to find out what the forecast is for water and weather conditions. Don't rely on the Weather Channel for accurate weather reports, as they're often reporting Oahu weather. If you happen to arrive during a North Shore lull in the surf, you'll want to plan to be on the ocean in a kayak or snorkeling on the reef. If it's raining, ATV tours are the activity of choice.
For the golfer in the family, Kauai's spectacular courses are rated among the most scenic, as well as the most technical. Princeville Golf Course has garnered accolades from numerous national publications, and Poipu Bay Golf Course hosted the prestigious season-end PGA Grand Slam of Golf for 13 years, although Tiger (he won a record five-straight tournaments) and company, unfortunately, now head to Bermuda for this tourney.
One of the most popular Kauai experiences is to see the island from the air. In an hour or so, you can see waterfalls, craters, and other places that are inaccessible even by hiking trails (some say that 70% or more of the island is inaccessible). The majority of flights depart from the Lihue airport and follow a clockwise pattern around the island. If you plan to take an aerial tour, it's a good idea to fly when you first arrive, rather than saving it for the end of your trip. It will help you visualize what's where on the island, and it may help you decide what you want to see from a closer vantage point during your stay. Be prepared to relive your flight in dreams for the rest of your life. The most popular flight is 60 minutes long.
